Incredibly stubborn first timer here lol.
I’ve switched to using a liquid fertilizer with little nitrogen about once a week highly diluted into the water. I water just a little bit every day or every other day. I shake the stems and diddle the flowers trying to get them to self pollinate every day. Most of the plants have active flowering but. I’ve only had two start to fruit and it’s one fruit on one plant and 3 tiny fruits on another. The lights are timed to around 16hrs on, 8hrs off every day. I sometimes open the tent and air it out with a rotating fan just for the hell of it but it’s not too hot or humid in the grow tent. They were all planted between 7/21 and 8/2. Is it just too soon or what am I missing?

What state/country are you in?
They look in pretty bad shape. Not enough light and water and not enough or too many nutrients (hard to say — if they’re in pots and you’re fertilizing every other day that’s way too much). Possibly not enough room for the roots either, but I can’t see what they’re planted in from the photos.
G’Day mate,
Are you set on growing indoors or is there a reason local to you that you can’t grow outdoors, like it’s too hot or too cold or poor soil, pests, etc?
Growing indoors can be fantastic but it has it’s own set of problems that come with the territory, you’ve already mentioned a few, airflow, temperature, humidity. Another consideration is the power of your lamps vs the type of plant you want to grow.
From what I understand, before the development of LED lamps for plants, you can grow a neat little weed plant with a 400w HID lamp, or you can grow a really big weed plant with a 1000w HID lamp. Great, but what’s that got to do with tomatoes.
The product that your harvesting from weed is a flower, the product you are harvesting from a tomato is a fruit. I’m not a plant biologist but to my layman’s mind it stands to reason that a fruit, or many fruit loaded with carbohydrates and nutrients are going to be more energy taxing to a plant than developing many flowers, therefore it stands to reason that a tomato might need more energy than say, a lettuce, or indeed a weed plant.
I apologise if you’ve got an idea about all this and I’ve just spent a bunch of time teaching you to suck eggs, but if not: Tell me about your lamp. Whatcha got?
Double the light go up to 18 hrs light then cut it back by 15 minutes every few days until you get to 15 hrs light that should signal it to get in gear.
They look dry. Are you pollinating them?
My immediate thought would be too many suckers stealing energy and not enough light. Unless you’ve got really big pots and good lighting, you probably don’t want to let an indeterminate tomato just run wild with no pruning. They can absolutely be grown indoors successfully but they have a smaller battery and a smaller charger compared to outdoors under the sun and in the ground so you’ve gotta deal with them with that in mind.
Pollination?
